…
The truth Qiong Xiao wants to explain is actually very simple.
If a piece of iron weighing 10,000 kilograms is cut into several parts and dropped together, will the falling speeds of these parts be different?
With a little experimentation, you can basically determine which one will fall faster between an iron block weighing 10,000 kilograms and one hundred kilograms...
Bixiao was not stupid. After seeing Qiongxiao's operation, he realized it instantly.
The three women communicated and experimented together, and soon they fully understood how miraculous the "gravity" Chu Xiu mentioned was.
"The process of falling also has a fixed value similar to pi. Through this fixed value, the speed of falling can be calculated." Yun Xiao said in a deep voice.
"Yes, this value is different from pi. It can be deduced." Qiong Xiao nodded.
Bixiao said: "Actually, it's not accurate. The falling process seems to be related to the wind. Even if there is no wind, it seems that it cannot be completely... free when falling."
"It can be compared to falling into water. There is also matter in the void, blocking the fall." Yun Xiao said thoughtfully.
"..."
The three women were very involved in the exchange, and their eyes were faintly shining.
Chu Xiu seemed to have opened a new door for them.
For them...
Physics, very interesting.
When Chu Xiu took Yun Ran'er's hand and arrived near the boundary of heaven and earth, the three women were deducing pi together.
The void has been filled with numbers.
"This is this?" Yun Ran'er looked at it briefly, then her heart suddenly moved, and she couldn't help but glance at Chu Xiu.
"I gave them a question to calculate the relationship between the circumference and diameter of a circle." Chu Xiu smiled and said.
The endless string of numbers suddenly appeared in the back of Yun Ran'er's mind, and she chuckled: "Then you are really bad."
At the same time, there was some unspeakable joy in my heart.
She now fully understood why this junior brother gave her such a pen.
When she draws a circle with that pen, pi will instantly be deduced automatically in her mind to an infinite degree.
Yun Ran'er's voice woke up Sanxiao who was intoxicated in deducing pi.
Sanxiao all turned around, and the moment they saw Chu Xiu, their eyes lit up.
After seeing Yun Ran'er's outfit, her eyes lit up again.
"Why did you appear from behind us?" Bixiao asked curiously.
During the questioning, the three girls, Yunxiao, Qiongxiao, and Bixiao, had already gathered near Chu Xiu and Yun Raner.
Chu Xiu said truthfully: "After I entered the boundary of heaven and earth, I kept running forward along a straight line. At the end, for some reason, I went directly back to the stone wall where I entered Cangyuan Domain."
"..."
The three girls, Yunxiao, Qiongxiao, and Bixiao, looked at each other with a bit of confusion in their eyes.
"This is my ninth senior sister Yun Ran'er." Chu Xiu, Yun Ran'er and San Xiao introduced each other, "They are the three fairies Yun Xiao, Qiong Xiao and Bi Xiao."
The three girls, Yunxiao, Qiongxiao, and Bixiao, all looked at Yun Ran'er, and Yun Ran'er did the same.
The four women nodded slightly at the same time, which was regarded as greeting each other.
"Fairy Ran'er's clothes are really unique." Qiong Xiao looked at the white shirt, black skirt and black silk that Yun Ran'er was wearing, her eyes full of novelty.
The same is true for Yunxiao and Bixiao. They are both women, and they are actually quite interested in dressing up.
Even though he is as steady as Yunxiao, he still cares about his own image.
Yun Ran'er remained calm, looked down at herself, then looked at Sanxiao, and said with a smile, "The clothes of the three fairies are so beautiful that they are far beyond what I can match."
"Fairy Ran'er is so humble." Yun Xiao said softly.
"Are all the women over there dressed as beautifully as you?" Bixiao asked curiously. The more he looked at Yun Ran'er's clothes, the more beautiful she felt and had a different kind of attraction.
Yun Ran'er chuckled and said, "That's not true. This outfit was specially chosen for me by my junior brother."
Yun Xiao, Qiong Xiao, and Bi Xiao's eyes subconsciously fell on Chu Xiu.
"Senior sister is naturally beautiful and looks good in anything she wears." Chu Xiu praised her.
"Let's talk business." Yun Ran'er smiled.
Chu Xiu nodded and looked at Sanxiao, "Have you been waiting here?"
"We promised you." Yun Xiao said softly.
"I'll draw all the places I passed after entering Cangyuan Domain. Take a look..." Chu Xiu muttered, and then, with a slight movement of his right hand, a huge piece of drawing paper appeared under the four people's feet.
On the painting paper, mountains, rivers and lakes gradually rise.
"Let's supplement it." Bixiao said softly, and then together with Yunxiao and Qiongxiao, they drew a complete picture of the terrain of Cangyuan Territory by swiping on the paper.
Chu Xiu and Yun Raner looked at each other.
"I'll do it." Yun Ran'er said softly, then went to the starting point drawn by Chu Xiu on the drawing paper and began to outline the situation in Cangyuan Valley.
Yunxiao, Qiongxiao, and Bixiao were willing to draw the entire Cangyuan Territory. Naturally, she and her junior brother needed to reciprocate the favor and draw some of the luxuriant terrain and scenery of the Nineteen Prefectures of the Wilderness Territory.
As soon as the four women were painted, Chu Xiu immediately transformed the flat painting into a three-dimensional image.
Mountains and lakes seemed to come alive.
"This is the Cangyuan Wall. After I passed through here, I lay directly in the valley of the Cangyuan Domain." Chu Xiu pointed at the Cangyuan Wall on the drawing paper, and then he flicked his finger. There is an extra little person. This little person runs quickly along the path he walked before, leaving a long and winding yellow line on the drawing paper.
When he reached the boundary between heaven and earth on the drawing paper, the villain rushed in directly.
At the same time, Chu Xiu quickly sketched the inside of the boundary between heaven and earth, simulating the real boundary between heaven and earth.
"I'm pretty sure that I walked along a straight path." Chu Xiu said softly, "But when I walked out of the border, I appeared directly on the Cangyuan Wall."
As he spoke, Chu Xiu drew an arrow on the deepest boundary between heaven and earth on the drawing paper, and also drew an arrow on the other side of the Cangyuan wall.
"..."
Yunxiao, Qiongxiao, and Bixiao all looked at the situation in the boundary of heaven and earth curiously. They couldn't understand why they appeared on the other side of Cangyuan Wall after crossing the boundary of heaven and earth.
Judging from this drawing, these two places are very far apart, and one is in the east and the other is in the west. How can we reach the east if we keep going west.
Yun Ran'er stared at the drawing paper and pondered in silence. The spherical world that her junior brother Chu Xiu had described before kept popping up in her mind.
In her opinion, if this square of heaven and earth is spherical, then if you keep walking in the same direction, you will definitely be able to return to the starting point after going around enough times.
"Is it a ball?" Although she was inclined to guess in her heart, however, seeing the attitude of her junior brother Chu Xiu, she was not sure.
She knew very well that her junior brother's strength far exceeded hers.
If this Cangyuan Domain is really a spherical world, it is unlikely that the junior brother will not notice it.
Yunxiao stared at everything on the drawing paper, her eyes frequently falling on the Cangyuan Wall and the boundary between heaven and earth. She hesitated: "Actually, a long time ago, I once saw an ancient legend in a ruins."
"What legend?" Chu Xiu was curious, and Yun Ran'er also looked at Yun Xiao curiously.
"The ancient legend says that this square of heaven and earth is actually a painting."
